Man-machine Cooperation Model Of Table Tennis Robot Competition System

With the rapid development of robot technology, binocular vision technology and wireless network technology, binocular vision technology and robot technology in the field of national defense, industrial manufacturing and industrial production, and sports field have a wide range of applications.Traditional sports game is a man of the match and the robot imitates the human race, and human robot interaction of sports is a new type of sports, both human and robot as independent players to cooperate and form of cooperation is man and the robot can perform the same game or associated game. Man-machine cooperation mode table tennis robot competition system is a composite tournament man-machine cooperation competition system on the basis of traditional table tennis stacking robot interactive movement motion, robot intercept or avoid. The system changes the ping pong table settings, increase interest points, the increase in the environment of wireless network and Internet, achieve multi pattern competition. In the system including the binocular camera for table tennis of3D trajectory recognition; table tennis robot is built, according to table tennis track placement control robot fight or escape, or the robot to do cheerleaders, race gap painting; recording the whole game process, save the video, in controversial when the playback video; establish an interactive platform for the audience, the audience can watch the game through the network, and vote and comment on their support for the team; the whole system through the network interactive.Through reading professional books and numerous papers by research on table tennis, binocular vision technology and robot technology. Analysis and the design of the man-machine cooperation mode table tennis robot contest system. The robot movement and table tennis games are interactive, and the design is divided into three parts:robot control, image processing and web design.. Robot control part of the main contents are:the "Creative Star" to build a modular robot, in Linux C language environment to write the PLC control program and in VS2010environment written human-computer interaction interface of the MFC, through a wireless network control robot motion. Image processing part of the main contents are recorded video games, and video playback. The binocular camera for calibration, stereo calibration and matching table tennis3D space coordinate is obtained according to the parallax. Using MATLAB for camera calibration (Zhang Zhengyou calibration method), the and the use of OpenCV prepared algorithm for stereo calibration and matching; through binary image and adjust the color threshold to partition a table tennis ball and the robot, and then according to the edge detection and contour extraction for accurate identification; through experiments proved the effectiveness of the algorithm. By DreamweaverCS6and PHP dynamic web development and website content including video game playing, users vote, choose the support table tennis team (the blue team and the red team), and online comments, expression to watch the mood of the game to interact.
